1 Claim. 1

This invention relates to improvements in a vehicle bed and has particular reference to a wagon box having a discharge conveyor adapted to be operated by means of a tractor power takeoff to unload said box.

The principal object of the present invention is the provision of a wagon box provided with an apertured bottom having swinging closures adapted to normally close said apertures, and having manually operable means whereby said closures may be selectively operated to control the rate of unloading of said vehicle bed.

Another object of this invention is the provision of a vehicle bed having a series of valve controlled outlets, manually operable to deliver adapted to control the flow of material from said box in the direction of movement of a power driven discharge conveyor carried therebelow.

Other objects are simplicity and economy of construction, ease and efficiency of operation,

and adaptability to handle various types and sizes of materials.

With these objects in view, as well as other objects which will appear during the course of the specification, reference will be had to the drawings, wherein:

Figure 1 is an elevational view of the right side elevation of the wagon box mounted on a running gear having parts broken away, and with certain of the parts shown in dotted lines.

Fig. 2 is an elevational view of the left side of the wagon box, with parts broken away and with some parts shown in dotted lines.

Fig. 3 is an enlarged cross sectional view taken on line III-III of Fig. 2.

Fig. 4 is an enlarged, foreshortened longitudinal view taken on line IVIV of Fig. 3.

Fig. 5 is an irregular sectional view taken on line VV of Fig. 4.

Fig. 6 is an enlarged sectional view taken on line VI-VI of Fig. 3.

Fig. '7 is a sectional view taken on line VII-VII of Fig. 3.

Throughout the several views like reference characters refer to similar parts and the numeral l0 designates a wagon running gear having bolsters 12 mounted on wheels [4 and having upright standards l6. Wagon box 18 is not of conventional type, but comprises vertical side walls 20, downwardly and inwardly converging walls 22, and a bottom 24 which is provided with iongitudinally spaced apart apertures or openings 26. Each opening 26 is provided with a downwardly hinged closure 28 mounted on a shaft 30.

Extending vertically below bottom 24 is a pair of spaced apart side walls 32 and 34 each having at its respective lower edge a pair of outwardly projecting bearing channel members 35 adapted to be fitted over the adjacent bolsters for supporting the box in proper longitudinal relation to the running gear. Furthermore the bearing members 36 are fitted on the bolsters [2 between the standards Hi to present lateral movement of the box on the bolsters.

The shaft 30 projects beyond the ends of the closure 28 to extend through walls 32 and-34. Each wall is provided with a bearing plate 38 to receive the end portions of the shafts 30 as clearly shown in the side elevations of the box and in Fig. 5.

That portion of shaft 30 extending through wall 32 is provided with a fixed lever 40 to which one end of a helical spring 42 is attached while the opposite end of said spring is secured to pin 44 securely mounted in side wall 32. This spring is so positioned as to normally urge the closure 28 snugly against the lower surface of bottom plate 24 to effectually close the opening 26 formed therethrough. The other end of shaft 30 passing through wall 34 is provided with a fixed lever 46 having a spring actuated plunger pin 48 adapted to engage in recesses 50 formed in plate 52 secured to the outer surface of wall 34. The series of recesses 50 are disposed in an arcuate path concentric with the axis of shaft 30 and are so spaced that the upper recess 50 is adapted to receive pin 48 to secure the closure 28 in the closed position and the recesses therebelow allow for diiierent degrees of opening of the closures to regulate the flow of grain through openings 26.

Referring to Fig. 6 which shows an enlarged sectional view of the plunger engaging means for positioning the closure 28, it will be noted that lever 46 is provided with a hollow cylindrical head 5| open at its inner end to receive a threaded bearing disc 54 adapted to close the end of the head 5| and to serve as a bearing for pin 48 which also extends through a bearing 56 formed in the outer end of head 5|. Mounted on plunger pin 48 within head 5| is a collar 58 fixed to pin 48 by means of a pin 60. Positioned about pin 48 between collar 58 and bearing 56 is a compression spring 62 which serves to urge the pin 48 into recesses 50. To remove the pin 48 from the recess 50 the operator simply pulls the plunger pin cap 64 outwardly, moves the lever to the desired position, releases the cap 64 and permits the pin to engage in the desired recess 50.

An endless belt conveyor 66 is carried on sprocket wheel 68 carried on shafts I and 12 rotatably mounted respectively in bearings disposed adjacent the front and rear of said wagon box.

Shaft is mounted in bearings 14 rigidly secured'to the outer surfaces .of rwall'd32 and :34, 10 while shaft12- is mounted in-gear box housings l6 and '18 disposed respectively on walls 32 and 34 adjacent the rear end of the wagon box. Each of the shafts i0 and 12 are provided with ,.two, spaced apart sprocket wheels 68 disposed between 15 wall members 32 and 34 to operat'rvelymeceivee endless chains, 82 joined togetherbycross bars. or flights 84 preferably made of angle iron. The upper reach of conveyor 66 rests oniltop ofia.

It is evident that a single attachment to the tractor power take-off will drive all the moving parts of the device.

The manually controlled valves 28 may be selectively opened to unload the box l8 at any desired sequence.
